HandOfPaper: Sometimes beginners fail to notice when they have (salvageable) groups in atari. Can anyone comment on the kyu level (on average, I guess) by which this disappears?
Mef: Well, I'm supposedly about 3 kyu, and I still can't spot atari all the time...
Charles A better indicator would be awareness of snapback shapes, ahead of time. There are just a few basic patterns. A dan-level player should really always be aware of a snapback coming.
HandOfPaper: First of all, one question, Charles: do you mean notice a snapback coming a few moves ahead or at the last chance to connect out when the group only has 2 liberties left? When should the amateur notice? Something else I've heard of (from Zahlman) as an example of a difference between beginner play and amateur (and high-level beginner) play is the way that saving a group from death takes on significantly global considerations at higher levels while, at lower levels, saving a group from death remains a local problem.
Alex Weldon: There's already a page about this. See Rank and What You Know
HandOfPaper: Then should I take this down? What's the proper thing to do here? I apologize, but I am new to Sensei's Library.
